Hi everyone.
I had a deck which was bolted into the wood which sits on top of the concrete foundation of the house. I detached the deck from the house to fix an leak behind the deck.
There is a sono tube at the far corner from the house which was used to support the deck.
See below for pictures before and after removing the deck.
Now I need the deck to be put back up. However, this time I don't want to bolt it back into the wood any more.
I think there are 2 options to support the part of the deck against the house.
1) use wall anchors to bolt a piece of wood into the concrete wall. Secure another piece of wood on top of the original piece. Then put the deck up on top of the wood.
My concerns are:
- The wood is not able to breathe when they are right up against the concrete or right on top of each other. Will it rot?
- Will wall anchors damage the rebars in the concrete wall?
- Will wall anchors be difficult to remove or hide if I decide to upgrade the deck or put something else there in the future?
2) install a couple of more sono tubes by the house to support the deck. It's more expensive, but if it's a better option for the house, I will do it.
Concerns with this options are:
- Do I need to dig as deep as the footing of the house? (which is 5.5 feet deep)
- How far away should the tubes be from the house? Will it disturb any structure such weeping tile underground?
- Are there any disadvantages of installing sono tubes close to the house?
Any opinions would be greatly appreciated!
Cheers,
Paul
